— GLOBAL BESTSELLER BEARINGS
Plain Bearings
Plain bearings consist of bearing surfaces, sliding layers, housings, and optional lubrication structures designed for relative motion between components. Unlike rolling bearings, they operate through sliding contact to support loads and reduce friction. These bearings provide reliable performance in machinery requiring compact designs, low maintenance, and continuous operation across various industrial applications.

- Provide reliable operation through corrosion-resistant materials and protective designs.
Classification of Plain Bearings
Spherical Plain Bearings
Spherical plain bearings feature inner and outer rings with spherical sliding surfaces to allow angular movement and handle misalignment. Therefore, they can support radial and axial loads during oscillating operation. They are widely used in hydraulic cylinders, construction machinery, agricultural equipment, and heavy-duty industrial applications.
Rod End Plain Bearings
Rod end plain bearings combine a spherical plain bearing with a threaded housing to create compact connection solutions. In addition, they handle angular movement and alignment changes while transferring forces between components. They are commonly used in actuators, control systems, robotics, and mechanical linkage equipment.
Plain Bushings
Plain bushings use cylindrical sliding surfaces to support shafts and housings with simple designs. Furthermore, they provide low friction, good wear resistance, and easy installation. Depending on the material and lubrication method, they are suitable for automotive systems, industrial machinery, agricultural equipment, and general mechanical applications.
Linear Plain Bearings
Linear plain bearings provide linear motion through sliding surfaces without rolling elements. Meanwhile, their simple structure reduces maintenance requirements and supports compact equipment designs. They are commonly used in automation systems, linear guides, handling equipment, and industrial machines requiring smooth and reliable movement.
